I do
I've never saw a green star so yeah
Like the blue stars are named O-type stars
So maybe green ones should be named Q-type stars
And they are really extremely hot, hotter than the O stars
For the planets, I don't really know tbh
Maybe an orange with brown/black stripes planet? With a lot of volcanos there
Since there's a lot of volcanos, then the planet would be rich with granites and andesites
